Insomnia / sleep disorders are characterized by difficulty falling asleep and/or staying asleep, waking up often during the night, waking up too early in the morning and feeling tired upon waking. It could take a toll on the ability to function during the day and cause an irritability, depression or anxiety. For patients with sleep disorders it is often difficult to pay attention, to focus on tasks or to remember. Insomnia also could cause tension headaches and due to the reduced attention it could increase errors and accidents. Insomnia may be an independent disorder or secondary to a medical condition.
One distinguishes two forms of insomnia: The primary and the secondary Insomnia.
Moreover one distinguishes between acute and chronic Insomnia. It varies in how long it lasts and how often it occurs. It can come and go and there might be times when a patient has no sleep problems. It varies in how long it lasts and how often it occurs.

The causes of an acute Insomnia can include:
The causes of a chronic Insomnia can include:
Another reason is the type of sleep. Indeed the profundity and length of a sleep characterizes its quality. Our sleep cycle distinguishes two main phases: The NREM (Non rapid eye movement) phase that has 4 stages going from light sleep to deep sleep and lasts for 90 minutes. This phase helps the body to regenerate.
The REM (Rapid eye movement) phase, also known as the dream sleep, that helps to deal with events and emotions endured during the day. A person does not feel rested even if he/she slept 8 hours because the cycle was interrupted: When the person wakes up in the moment of the NREM deep sleep phase, he/she can feel not having got a good night’s rest. Also the regeneration of the body can be affected if the person is not able to reach the deep phase after going to sleep and instead wakes constantly up.
Finally sleep disorders can also be caused by external disruptive factors: Too low room temperature, too flat/high or too soft/hard pillow, too hard/soft mattress, a ‘low breathable’ duvet are factors of sleep discomfort. Here are some recommendations: It is recommended to air the room before going to sleep. It is important to choose a Pillow that allows the spine to be perfectly aligned.
You should use a medium-firm mattress to avoid muscles pressure and offer support to back, neck and legs. If possible, choose duvets made from natural materials (feather, silk, cotton) as they are more breathable and avoid the person to perspire, wake up and have the sleep disturbed.
Polysomnography is a powerful tool to diagnose sleep disorders. Polysomnography is a comprehensive recording of physiological changes that occur during sleep such as brain waves, oxygen level in the blood, heart rate and breathing rate as well as eye and leg movement. It is used to diagnose or rule out many types of sleep disorders, including Narcolepsy, Restless legs movements, REM behavior, Parasomnias, somnambulism, epilepsy related disease, snoring and sleep apnoea. On the other hand, stress related or other psychiatric disturbances may cause sleep disorders or vice versa, just as inappropriate bedding.
For all these reasons it is of the utmost importance to analyse sleep and sleeping customs thoroughly in order to determine by aid of the neurologist the individually correct diagnosis and ensuing possibilities of treatment for sleep disorders. The sole application of sleeping drugs does not represent an ideal solution but may even be dangerous because it could lead to dependencies as unwanted side-effect.
There are no major preparations necessary. The patient is advised not to take any sleep medicine or drink alcohol or caffeinated beverages prior to this test.
Polysomnography is a non invasive procedure. There is no risk, except maybe some skin irritation caused by the adhesive used to attach the sensors to the skin. It is therefore a fabulous procedure for children too.
Physiologic sensor leads are placed on the patient in order to record the following:
For the standard test, the patient – suffering from sleep disorders – comes to a sleep lab in the early evening, and over the next 1–2 hours is introduced to the setting and “wiring up” so that multiple channels of data can be recorded when he/she falls asleep. The sleep lab may be in a hospital, or in a center. A sleep technician should always be in attendance and is responsible for attaching the electrodes to the patient and monitoring the patient during the study. She must explain to the patient about the procedure to keep the patient relaxed throughout the night.
The sleep laboratory should be equipped with video cameras in the patient’s room, so that the patient can be recorded while sleeping. This allows the technician to review the tape at any time during the test and verify whether strange looking waveforms were caused by an actual arousal, a period of wake, or normal patient movements in bed.
Nowadays, neurologists may carry out home studies to enhance patient comfort and reduce expenses, which is in the best interest of any patient. The patient is given thorough instructions as to how the screening tool is used. He will then use the equipment at home in his usual sleep surroundings and return it the next day. Most screening tools consist of an airflow measuring device (thermistor) and a blood oxygen monitoring device (pulse oximeter).
They are small and easy to handle and produce excellent graphs and other results. At the German Neuroscience Center our neurologists follow this new path and provide patients – suffering from sleep disorders – with a tool they can easily apply at home rather than putting the patient into an awkward situation at the clinic because they realize that especially in Arabic countries with prayer times and similar rules to follow, it might be difficult for the patient to carry out a sleep study outside their homes.
The patient will sleep with the screening device for one to three nights, and then return the device to the neurologist. The neurologist will retrieve data from the device and can make assumptions based on the information given, for example, a series of drastic blood oxygen desaturations during night periods may indicate some form of respiratory event (apnea). At a minimum, the equipment will monitor the oxygen saturation.
There are very effective ways of treatment for sleep disorders these days. The problem is rather that patients are hesitant to search professional help. Thus a vicious circle could start where the sufferer is already afraid of going to bed. Obviously then it will be very difficult to fall asleep. Specialists are using a combination of these scientifically proven treatment options for insomnia:
Stimulus control therapy is very effective and successfully used since more than 30 years. It sounds easy but it’s not. The pivotal point is your willpower to maintain these rules. It is actual work. If you don’t manage it alone, a psychologist might help you.
Insomnia and sleep disorders are widespread issues, affecting millions of individuals globally, with Dubai’s high-paced environment making it no exception. These conditions can lead to difficulties falling asleep, staying asleep, and can impact one’s daily life, causing irritability, depression, and anxiety.
At GNC Dubai, we recognize the importance of addressing these sleep-related challenges. Our team of dedicated professionals, including neurologists, is committed to helping you find effective solutions.
